A solution of (1aRS,7bSR)-5-(2-fluorobenzenesulfonylamino)-1,1a,2,7b-tetrahydrocyclopropa-[c]chromene-4-carboxylic acid (Intermediate 67, 0.6 g) and (S)-1-azabicyclo[2.2.2]oct-3-ylamine (6.0 g) in DMSO (6 mL) was stirred and heated in a sealed vessel at 140° C. for 22 hours. After cooling, the mixture was diluted with methanol and concentrated under vacuum. The residue was purified by HPLC (C18) to give (1aRS,7bSR)-5-{2-[((S)-1-azabicyclo[2.2.2]oct-3-yl)amino]benzenesulfonylamino}-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-4-carboxylic acid (0.107 g) as a white solid.
